Popular features of the Apple iPhone 5s are the high resolution retina display and the fingerprint sensor built into the home button for identity verification. Additionally, the phones feature an 8-megapixel iSight camera with 1080p HD video recording capability.
The high resolution Retina display has a resolution of 1136 x 640 pixels with 326 pixels per inch. With this resolution, it is extremely difficult to discern actual pixels while the phone is held at a natural distance from the eyes. It is a multi-touch display with an oleophobic coating on the glass that repels fingerprints.
The home button has a built-in sensor with fingerprint reading capability. The fingerprint sensor quickly verifies the phone user's identity before tasks such as unlocking the home screen and authorizing purchases in the iTunes Store, App Store or at brick-and-mortar stores using Apple Pay.
The 8-megapixel iSight camera has a state-of-the-art sapphire crystal lens and True Tone flash that help yield more accurate colors in photos. The camera has the ability to film 1080p HD video at up to 60 frames per second and play the videos back in slow motion. The camera also has automatic focus and facial recognition, which yield more in-focus photos.
